Global Health Surveillance
Global health surveillance is the systematic collection, analysis, and sharing of health data across countries to monitor and detect patterns of diseases and health threats. It helps public health authorities identify outbreaks early, track the spread of illnesses, and coordinate responses to protect populations worldwide. By using tools like reports, lab tests, and digital data, surveillance provides essential insights to prevent and control health emergencies, ultimately supporting a healthier global community through timely information and action.
